To all whom t may conce-rn.' l

Be it known that I, ROBERT L. SToKEs, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful also illustrated by the accompanying drawing in which like reference characters represent like parts in all figures,

Figure 1 is a vertical section of ymy 1nvention showing the float and float stem 1n elevation. Fig. 2 is a detached view in elee vation of the rod of Fig. 1. Fig. 3 is a detached view in elevation of the flat rectangu-j lar-shaped end of the lioat valve lever of Fi l. Y

is the bottom of the flushing tank.

B is the inlet pipe. Y l

C is a separate downward extension of the inlet pipe.

D is the oat valve water cup.

E is the anti-hammer stand pipe.

.1 is a flange-headed extension of the inlet pipe B. p

2 is a nut that binds the washers 3 and 5 and flange 6 lto, the bottom of the iushing 7 is a double collar, one portion of which is mounted on the inlet pipe B and the other portion of which is mounted on the eXtensionC. 9 is a bore through that portion of said 'collar connecting lthe two collars proper, said bore forming a bearing for the rod 10. 8 isa screw adapted to bind said collarto said inlet pipe.

11 is a foot attached to the lower end of the rod 10. 12 is a recess in said foot adapted to receive the end of the rod 13, said foot being adapted to support said rod 13, which in turn is adapted to carry and support the valve 15, comprising a recessed headl or cup in which the valve seat 14 is seated and the rubber bag 16 whichH vis'positioned within the anti-hammer E. f

17 is a circular boss encompassing the mouth of the outlet opening 18 of said water cup D and adapted to engage the valve seat 14 and cut off the flow of water from the inlet pipe B into the extension C.

19' is a cap adapted to screw onto and securely close the upper end` of the anti-ham- `mer E.

20 is a guidethrough which passes the upper end'21'of the rodl3 andwhich is adapted to admit a flow of water from the water cup D into ythe anti-hammer E at the moment of the closing vof the valve 15.

22, 23,124, 25, 26, 27,728, a9 are threads adapted to effect the assembling of the variousparts,describedgabove. Y

30 is a valve actuating lever having the l flat, rectangular-shaped end 31 and the perforations 32 and 33 which respectively are adapted -to receivethe hooked end 34 of the rod 10 and theVstudpin 35, which stud-pin extends laterallyand integrally from the outside face of the water'c'up D and is adapted to ,support pivvotally, said lever 30 mountedl thereon.; The flat, rectangular-shaped. end 31 lof said lever'30 is adapted to retard lthe movementof said-'lever ,upward inthe water on the closingfof the valve 15, and thereby lessen the force ofthe impact of the water Y at the time ofthe closing of said valve. 36

l is a standard extending integrally andA laterally from the outsidefac'e of said water cup, said standard having a perforation through the freeend thereof. 37 is the armv ofA-the float 38 and is attached to said standardrby means of the pivotal screw 39. 40 is a screw extending transversely through said float stem and adapted to engage the valve actuating "lever 30 during the downward movement of the float. 41 and 42l are hangers adapted to vibrate on the pivotal screws 43 and 39 respectively, and are still furtheradapted to engage said valve actuating lever 30 atv certain points thereof during downward movement of the float. 44 is the bifurcated end of the stem 37 and is adapted to receive the free end of said standard to which it is attached by means of the pivotal screw 39. 45 is a standard rising integrally upwardv from said float arm 37. 46 is a locking set-screw passing transversely through said last named standard and is adapted to engage the upper end of said hanger 42 and prevent it from following the law of gravity at certain points of the travel of said stem upward and downward.

Having thus described my invention in detail and by illustration, I will now Vdescribe it as a working mechanism.

The flush valve having been opened, the water in the flushing tank has flowed out and the float 38 has descended to the point indicated in the drawing, and, by means of said screw 40 and said hangers 41 and 4:2, it has carried said valve actuating lever 30 down with it, thus opening the valve 15. lThe flush valve now being closed, the' water begins to fill the tank and the float 38 be- Y gins to rise and for a short way upward the lever 30 remains in engagement with the hanger 42 and the screw Il() Vas indicated in the drawing and the rst stage or step of closing the valve lll has begun. Were it not for the fact that the lever 30 is held down as aforesaid, the weight of the valve apparatus and the force of the inflowing water would close the valve almost instantly and a jarring noise would be produced by the sudden impact of the water against the` sides of the water pipes and the water cup D, and that too in spite of the anti-water hammer E. In so doing, the lever 8O would be brought rapidly upward, to prevent which Y or at least to arrest to a considerable extent this rapid movement upward of lever 30, the flat, rectangular-shaped terminal 31 is attached to this lever, but that is not enough,

and it is for this reason that the float arm 37 is attached directly over this valve actuating lever and the hangers and screw as aforesaid attached to this arm. At a point still farther upward the screw 40 leaves the terminal 31 behind, but the hanger 42 remains in engagement with it. At a still far ther point upward,the screw 46 engages the upper end of the hangerLQ, pushes it out of a direct perpendicular position and, following this movement, said valve actuating lever engages the shorter hanger 41. At a point still farther up, and at about the time the oat comes to a state of rest, said valve actuating lever again engages the hanger 41. Thus it is, right at the time when the float valve would have been very suddenly closed, by means of the aforesaid mechanism the closing is made by a more gradual and steadier gradation. At the time of the closing of the iioat valve as aforesaid, a certain portion of the water in the water cup D is forced through the guide 20 and into the anti-hammer E, where the sudden impact of this water is received by the elastic rubber bag 16, and itis in this way again that the danger of noise caused by the impact of the water as aforesaid is still further overcome. Consequently, by the combined operation of transversely and downwardly therethrough, .c

a standard extending integrally upward from said arm, a set-screw passing horizontally and transversely through said standard and in the same plane as that of said arm, a hanger pivoted on said arm and near said standard, another hanger having an upward-extending arm pivoted on said first named arm near said last named hanger and at the pivoted end of said stem, said screw and said hangers being adapted to engage a valve actuating lever and regulate its move ment upward, said set-screw being ada ted to engage the upper end of said hanger liaving an upward-extending arm and to force said hanger out of a perpendicular position.

3. ln a valve mechanism a valve actuating closing lever having a flat, rectangular- Vshaped free end adapted to retard the upward movement of said lever through the water of a ushing tank.

4;. In a Vvalve mechanism, a valve actuating lever having a flat, rectangular-shaped free end in combination with a float and a float arm, said arm consisting of an arm proper, a screw passing transversely and downwardly therethrough, a standard eX- tending integrally upward from said arm, a set-screw passing horizontally andV transversely through said standard and in the same plane asY that of said arm, a hanger pivoted on said arm and near said standard, another hanger having an upward-extending arm pivoted on said first-named arm near said last named hanger and at the pivoted end of said last named arm, said screw and said hangerbeing adapted to engage said valve actuating lever and regulate its movement upward, said set-screw being adapted to engage the upper end of said hanger having an upwardly extending arm and to force it out of a perpendicular position.

5. In a valve mechanism and in combination; a flushing tank; an inlet pipe having a separate downward extension; a water cup adapted to unite the 'upper' ends of said inlet pipe and said downward extension; an anti-water hammer device attached to said water cup; a rubber bag positioned within said anti-water hammer device; a valve stem positioned within said downward extension of said inlet pipe and extending upward through said water cup and into Said antiwater hammer device, said stem having mounted thereon a cup-shaped valve with a separate seat therein, said valve beingpositioned within said water cup; a valve actuating lever having a flat, rectangular,- shaped free end, the other end of said lever being mounted on a stud extending laterally from the outside face of said water cup, said lever having a perforation through the extreme end of such mounted end portion; a rod adapted to engage said perforation by means of a hooked upper end; a foot having a recess in its upper face attached to the lower end of said rod, said foot being adapted to support said valve stem which in turn is adapted to support the said rubber bag; a float and an arm therefor, said arm having a perforation through its free end, a screw passing through said arm near said float, a standard rising upward therefrom and a hanger depending therefrom near said screw, another hanger having an upwardextending arm depending therefrom near Said standard; a second standard extending integrally and laterally from the outside face of said water cup, said standard having a perforation through the free end thereof adapted to receive a screw, said screw being adapted to receive the perforated, bifurcated end of said float arm; said screw and said hangers of said float arm being adapted to Y engage said valve actuating lever, said screw passing through said first standard of said float stem being adapted to engage said up- Y ward-extending arm and push said hanger ROBERT L. sroKEs.
